STEVEN RADIMAK, OF NEW YORK, N. YA.

BRUSHING AND IPOLISHING MACHINE.

To all w/zom it 'may concern.'

Be it known that I, STEVEN RADIMAK, citizen of Hungary, residing at New York, in the count-y of New York and State of New York, have invented certain new and useful Improvements in Brushing and Polishing Machines, of which the following is a specification. i

Thisinvention relates to a brushing and polishing machine which may be used forv polishing and sweepingfloors, or for brushingw and cleaning other objects.

- he invention has for a general object to provide a novel and simple machine of this type.

More specific objects o'f the invention are to provide for thewaxing of one or more of the brushes when the machine is used to polish floors, and to provide a special arrangement of the bristles which improves the efficiency of the brushes.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more wheels 15 and llon the brush shafts and particularly set forth. y

Fig. 1 of the drawings is a side elevation of a brushing and polishing machine constructed according to the invention.

Fig. 2 is a front end view with broken into section.

' Fig. 3 is a plan view. y Fig. 4 is a partial elevational view of the rear portion of the machine and looking in the direction indicated by the arrows 4-4 in Fig. 2.

Fig. 5 is a plan view of a modified form. Fig. 6 is a side view of the modified form shown in Fig. 5.

Referring now to the drawing, my 1inproved brushing and polishing machine here comprises a rectangular box 1() Ihav1ng an open bottom through which a pair of rotary cylindrical brushes 11 and 1 2 project, the box being supported on these brushes. These brushes are rotated by an electric motor 13 suitably mounted in a box 10, a sprocket chain 14 being looped over suitable sprocket parts vthe rotor of the motor 13.

The material dislodged bythe brushes 11, 12 is sucked up through a pairof conduits 17 and 18 which have their intake ends l0- cated infront of the respective brushes and l speciiieation of Letters Patent.

shaft -24 and on the shaft 22 and the rotor of the motor 13.-

Located in the front of the box 10 is al tank 28 adapted to contain a polishing liquid. such as oil, which is fed to the front brush 12. Leading from thistank is a pipe 29 controlled by a valve 3() and extending along the top of the brush 12 as at 29 this pipe Patented May 30, 1922. Application med Juiy lao, 1921. serial No. 436,119.

having a series of small holes 31 spaced' therealong for discharge of the liquid on the brush.

Located in suitable proximity tothe rear brush 11 is a wax feeding device which comprises a guide-box'35 having its lower side open and located in close adjaence to the periphery of brush 11. This box 35 is adapted to contain and act as a guide for a cake of wax which is inserted in the open side thereof.l This cake of wax is pressed against the brush 12 by a follower 36 urged forwardly by the coiled expansion springs 37.

. The box 35 is adapted to be swung out of registry with the brush 12 when desired, and to this end it is hinged at its upper side as at 38 to arms 39 fixed to box 10.

To prevent ythe cake of wax from being discharged by springs 37 from the box 35 when the latter is swung away froinbrush 12 a plate 40 is fixed to the rear end of the main box 10, this plate being arranged with a curvature concentric to the pivot point 38 of the box 35 and being suitably positioned with respect to brush 11. To hold the box 35 in the desired position a latch is provided in the form 0f a handwheel 42 to which is fixed a finger'` 43. This finger 43 may be engaged either over the front edge of the plate 40, as shown 'in' Fig. 1. or in a slotv 44 adjacent the outer edge of the plate.

As shown in Fig. 2 the brushes 11, 12 preferably have the bristles spaced more closely together at the end s than at the centre, this arrangement acting to prevent tendency of the device to tilt sideways when being moved along the floor or other surface.

The brushes also 'preferably have rubber washers at the ends thereof partially overlapping the bristles. Hinged adjacent each brush 11, l2 is a comb 45 which may be svvung into engagement with the brush to dislodge material therefrom and cause it to be directed into the adjacent chute.

For running the device along the floor it may have a bail 48 hinged thereto' and provided With an elongated push handle 49.

In the modification shown in Figs. 5 and 6 a single brush 60 is provided, being driven by a motor 61, which also drives a suction fan 62 in a conduit 63. In this modified form the box 64 is provided with a pair of fixed handles 65 which may be grasped by the user.

Having thus described my invention what I claim as new and desire to protect by Letters Patent of the United States -is as follows:

- ing liquid on the other brush.

brushes mounted in said box, a tank 2. In a device of the class described, a pair of, rotary brushes arranged one before the other, means for delivering a polishmg liquid on the front brush and means for supporting a cake vof v'Wax in contact with the rear brush.

f3. In a device of the class described, a pair of rotary brushes located `one inad- Vance of the other, and means for applying oil to the front brush and Wax tothe rear 4. A device of the class described com? prising a box, a pair of rotary cylindrical for a polishing liquid in saidr box, a perforated P1Pe parallel to one of lsaid brushes, and a guide Wax located adjacent to the other brush.

.leading from said tankv above and 5. A device of the class described oomprising a box, a pair of rotary cylindrical brushes mounted in said box, a tank for polishing liquid in said box, a'perforated pipe leading from said tank above and parallel to one of said brushes, and a` guide box other brush, and a spring pressed follower in said guide box.

6. A device of the class described comprising a box, a pair of rotary cylindrical brushes mounted in said box, a tank for a polishing liquid in said box, a perforated pipe leading from said tank above and parallel to one of said brushes, and a guide box for a cake of Wax located adjacent the other brush, and a spring pressed follower in said guide box, said uide box having one side open and being hinged at its opposite side, and a retainer plate adapted to register for a cake of wax located adjacent the l with the open end of the guide box when the latter is swung out of registry with the said brush.

7. In a device of the class described, a rotary cylindrical brush, a guide box for a cake of Wax hinged at one side and having its opposite side open and adapted to be swung into or outv of registry with the said brush, and a retainer plate curved concentric to the pivot point of the guide boxA 8. In a device of the class described, a rotary cylindrical brush, a guide box for 'a cake of Wax hinged at one vside and having its opposite side open and adapted to be4 swung into or out of registry With the said brush, and a retainer plate'curved concentric to" the pivot point of the guide box, said .re-

tainer plate having a slot'therein, a hand Wheel pivoted on said box, and a finger fixed to said hand wheel andadapted to engage in saidslot.

,In testimony whereof I have aliixed my signature.
